Nailfold capillaroscopy in leprosy*
Due to mounting evidences of interaction between Hansen's bacilli with endothelial cells and the paucity of studies addressing the presence of nailfold capillaroscopic alterations in patients with Hansen's disease, a study was carried out in order to verify the presence of capillaroscopic alterations in patients with leprosy in its various forms and its correlation with clinical parameters. Ten...
متن کاملNailfold capillaroscopy as a diagnostic and prognostic method in rosacea.
BACKGROUND There is no appropriate and reliable method of evaluating and monitoring severity in rosacea. OBJECTIVE To determine the importance of nailfold capillaroscopy as a diagnostic and prognostic method for patients with rosacea. METHODS A cross-sectional study where eight patients with rosacea and 8 control subjects were submitted to nailfold capillaroscopy from May to July 2009. We c...
متن کاملAutomated Categorisation of Nailfold Capillaroscopy Images
Nailfold capillaroscopy (NC) is a non-invasive imaging technique employed to assess the condition of blood capillaries in the nailfold. It is particularly useful for early detection of scleroderma spectrum disorders and evaluation of Raynaud’s phenomenon. While automated approaches to analysing NC images are relatively rare, they are typically based on extraction and analysis of individual capi...
متن کاملComputer-Aided Analysis of Nailfold Capillaroscopy Images
Nailfold capillaroscopy (NC) is a non-invasive imaging technique employed to assess the condition of blood capillaries in the nailfold, and is routinely used for the detection of scleroderma spectral disorders, Raynaud’s phenomenon and other connective tissue diseases. In this chapter, we present computer-aided approaches for capillary inspection, in particular focussing on the tasks of image e...
متن کاملMicrovascular abnormalities in Sjögren's syndrome: nailfold capillaroscopy.
OBJECTIVE To describe microvascular abnormalities by nailfold capillaroscopy in patients with primary Sjögren's syndrome (SS) with or without Raynaud's phenomenon (RP) and those with anticentromere antibodies (ACA). METHODS Forty patients with SS (14 without RP, 16 with RP, 10 with ACA), 20 patients with scleroderma (SSc) (10 with limited and 10 with diffuse disease) (disease control group) a...
